| Peak-Sensing Discriminator for Multichannel Detectors with Cross-Talk | ||
| Protvino, 1998.- p.12, figs. 12, refs.:12. | ||
In view of handling the anode signals from the position-sensitive photomultiplier a new front-end electronic circuit has been designed and realized, which allows one to suppress annoying effects of the cross-talk between adjacent channels. The circuit was tested in association with a scintillating-fibre detector in a test beam at CERN. The basic performances, such as the detection efficiency and its uniformity, as well as the hit multiplicity for single tracks were compared to those of the conventional electronics based on the simple threshold discriminators. A great advantage of the peak-sensing circuit was experimentally demonstrated in particular in its real time digitization of the track position without significant ambiguity of the track position due to the cross-talk.
